Let M cos(y) y cos(x) and N sin(x) - x sin(y). Then. Since these are equal, the DE is exact and. Now. and the implicit solution is x cos(y) y sin(x) C.Then we get the system dy/dx z , dz/dx 2x2z - 4xy2 of two first order DEs. Youre given dy/dx sinx(cosx)2.
you can "multiply" both sides by dx. this "multiplication" works, but dont think of "dx" as a variable or somethingask your teacher - it s too hard to explain. so anyways, after multiplying by "dx", you should get a nicer equation: dy/ dx sinx(cosx)2 dy [sinx(cosx)2] The identit sin 2 x cos 2 x enables us to convert back and forth between even powers of sine and cosine. EXAMPLE 2 Find sin 5 x cos 2 x dx cos 3 x cos 2 x cos x sin 2 x cos x u 2 du u 3u 3 C sin x 3 sin 3 x C SOLUTION We could convert cos 2 x to sin 2 x Articles on "2sinx Cosx Sqrt 3 Sinx 0".
